Hi,

I have a .reg file which copies some menu items as keys in the registry. My dll collects all of them and show up on right click if i selected any thing on the explorer.

How to make my 32 bit com dll works in 64bit machine? I recompiled in 64 bit machine using visual studio 2008. It did not show up the right results. it is not showing up any menus on the right click.

Thanks in advance.

Regards,

Can't you debug the code and see what's happening?

Hi,

I run the program as administrator. Then I tried compiling solution in the vista 64it. It gave “error PRJ0019: A tool returned an error code from "Performing registration"”. When I comment the following code

STDAPI DllRegisterServer(void)
{
               AFX_MANAGE_STATE(AfxGetStaticModuleState()); 
    // registers object, typelib and all interfaces in typelib
    return _Module.RegisterServer(TRUE); //this is what  I commented 
return TRUE
               
}

it compiled successfully. This is com dll which is working fine in 32 bit.
what should i do now?

This could be some dependency issue. Check the dependecy of the DLLs/components associated with this COM DLL and ensure that it's built using 64 bit environment. Check with Dependency Walker[^]tool ( 64 bit version is available).

Also try manually using regsvr

Hi,

Thanks for your suggestion. I ran dependency walker in 2003 64 bit for my dll. it displayed two errors in the following dlls

DEVMGR.DLL
DWMAPI.DLL.

it says "error opening file". Don't we have these dll's along with 64 bit 2003 os?

Regards

I don't know about DWMAPI.DLL but the other one should be there in the system folder. Do one thing, in the 32 bit system, try to track down, from where these files are getting resolved using depends. Then you can try the same thing in 64-bit environment also

Hi Sarath,

I created the application by following the below link
http://www.codeproject.com/KB/shell/shellextguide1.aspx?fid=519&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=2469014#modifyingmenu[^]

but the same is not working in my 64 bit windows 2003 server.

How to migrate this application?

I can't figure out what's really happening there. The IContextMenu inteface should work well with your application. Have properly set set _WIN32_WINNT and WINVER macros? According to your target OS?

Hi all,

How can I set a partition as active partition using c++ code?
Is there any API or function to do that?

Please guide me with your comments.

thanks.

I suspect DeviceIoControl[^] and the IOCTL_DISK_SET_PARTITION_INFO_EX[^] control code may point you in the right direction. I don't know if they'll actually let you do what you want, though - that function may only be accessible through lower level NT functions that are (publicly) undocumented, or documented in the device driver documentation?

In fact, looking a bit further, I suspect IoSetPartitionInformationEx[^] is probably the function you need - but that's part of the NT API, not the Win32 API.

The details of all installed applications are stored in registry under,
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall

Since you have a preference for C Compiler, You can use plain windows api to read the registry and populate the list. This article[^] will be helpful.

you can right click on the dialog and select Insert ActiveX Control and select the windows media player activex.

once its selected then create a member variable for it. you get all the wrapper classes that is required for the activex component to work properly.
